4. INTRODUCTION TO BLUETOOTH ® “PAIRING”
What is Bluetooth® wireless technology?
Bluetooth® wireless technology is a radio technology that connects devices,
such as mobile phones and headsets, without wires or cords over a short
distance of approximately 10 meters (approx. 33 feet). Get more information
What is Bluetooth® wireless profiles?
Bluetooth® wireless profiles are the different ways that Bluetooth® devices
communicate with other devices. The Transmitter supportsA2DP andAVRCP
in order to allow music streaming and playback control. Please refer chapter
“Music Streaming and Playback Control” on page 17 for more description
on these profiles.
What is pairing?
Pairing creates a unique and encrypted link between two Bluetooth® devices
and lets them communicate with each other. Bluetooth® devices will not work
if the devices have not been paired.
Pairing Sequence
Note: Please refer to Clarion Bluetooth® Audio/Mobile-phone Transceiver for
AUX Input owner’s manual for the relevant operation below.
Between Bluetooth® Audio/Mobile-phone Transceiver and
Bluetooth® Audio Transmitter

“Setting Up DGL373” on page 7.
2. Make sure the car stereo source mode is switched to “AUX” mode.
3. Set the Transceiver unit in pairing mode.
4. Set the Transmitter unit in pairing mode. Please refer “Activating Bluetooth®

4. INTRODUCTION TO BLUETOOTH ® “PAIRING”
Notes:
• You cannot pair the Transmitter with your mobile phone.
• You do not have to enter a dedicated pin code for pairing these two devices, as
you do with a mobile phone.
• During pairing mode, the Transmitter unit should show a quick alternate red/blue
LED. Make sure that the Transmitter and Transceiver are not paired to any other
Transceiver or Transmitter respectively.
• Please refer “Understanding The Transmitter Unit Indicators” on page 13 for
further details.
Automatic Connection
When the Transmitter is switched on, it will automatically try to re-connect with
the last paired device (Transceiver unit). It may take up to several seconds for
the re-connection. If there is no connection detected after 3 minutes, Transmit-
ter will be automatically powered off.
If the device (Transceiver unit) already has connection with another device
using the same Bluetooth® profile (A2DP), automatic connection will be
failed.
Notes:
•
•
If the Transceiver is switched off and on, it may require 20-30 seconds for the
Transmitter to detect disconnection before re-connection.
Music streaming may be discontinued if the Transmitter and Transceiver are
moved out of range of each other.

5. OPERATIONS FOR BLUETOOTH ® AUDIO TRANSMITTER
Music Streaming and Playback Control
Music streaming is a technique for transferring audio data such that it can be
processed as a steady and continuous stream.
Users can stream music from their iPod or other external audio player to their
car stereo and listen to the tracks through the car’s speakers.
WHAT IS A2DP?
A2DP (Advanced Audio Distribution Profile) is a Bluetooth® profile that
allows you to send CD quality stereo music from one device to another without
wires.A2DP is able to provide crystal clear music without the hassle of plugging
cables. Bluetooth® wireless technology withA2DP makes this Transmitter unit
capable of streaming music.
WHAT IS AVRCP?
AVRCP (Audio Video Remote Control Profile) is another Bluetooth® profile
that enables music from external audio player to be controlled remotely.AVRCP
allows some basic playback control functions such as play/pause, volume
up/down and next/previous track to an external audio player.
! CAUTION
• The Transceiver works as one way communication to the Transmitter. Thus,
please avoid controlling the iPod (when Transmitter is used with iPod Cradle)
and Transceiver at the same time as this might cause some incorrespondence
operations between the both devices.
Notes:
• Please refer the Transceiver unit owner’s manual for more information onAVRCP
controloperations.ThisTransmitteronlysupportsplay/pauseandnext/previoustrack
for iPod.
• There is no volume control support from the analog output of 30-pin iPod connector
interface. Changing the volume on the iPod through the “wheel” control will have
no effect on the music streaming.
• There is no remote control to external audio player that connected to Transmitter
through 2.5mm audio jack input.
